Like I said, we don't need a fully general generic platform driver
right away.  If you make a small number of additions so that it is
clear how to use the two generic drivers instead of some of the
existing platform drivers, and then submit the generic drivers as a
separate standalone patch series, that should be good enough.  Greg
will probably be very happy to merge it, if it includes an explicit
plan for replacing some existing drivers.

Then the bcma stuff can be added on top, as a separate patch series.  
Once that's done, we can start making an effort to assimilate the
platform drivers into the generic drivers.
